“First of all, people don’t know about me, I’ve worked in media most of my life and in broadcasting,” Samantha insisted. “So because my sister is suddenly Royal isn’t grounds for me to stop doing all that.

“Let’s face it, we all have to survive, money makes the world go round, so if you want to call that cashing in, that’s fine. But no one in media would refuse a paycheck for talking about the Royals, and as a family, we’re not subject to Royal protocol, certainly here in America. If you want to call it cashing in, I think that’s a little bit ridiculous.”

Conversation then turned to ‘CBB’, to which Samantha said: “I’ve worked in media most of my life, why would I not? Why would I stop living because I have a family issue going on?

“I don’t think she’s intelligent enough to be able to separate the two, whether you’re a celebrity or a Royal, you have a high public profile and that’s subject to discussion within the media.

“Back to the issue of cashing in, the media make billions of dollars off social issues and talking about the Royals. I don’t see how we’re any different.”

She added: “No one has a copyright on our life experiences. We’re each individuals with our own life experience.

“With all due respect, it’s not just Meg, we’re entitled to share that, we’re entitled to be open about it, if we can shed some light on some issues for the public, then great. We can enjoy the process. I don’t think there’s anything wrong with that. It’s not disparaging, it’s not harmful.

“For someone to say, ‘Oh you shouldn’t take any money, you should turn down a paycheck’, go tell your boss you don’t want a paycheck for interviewing me because that’s cashing in.”

However, when asked to confirm that she was appearing on the series, which has an ‘Eye Of The Storm’ theme, featuring celebrity contestants caught up “in their own media storms”, Samantha joked: “I would tell you, but then I would have to kill you, so... I don’t want to find myself in locks and stocks, quite frankly.”

The most recent series of ‘CBB’ wrapped up in January, and had a ‘Year Of The Woman’ theme, with producers keen to change the tone of the show to make it more centred around serious debates relating to gender roles and sexism.
